INSTALLATION & OPERATING DATA
1 PRINCIPAL OPERATING FEATURES
The TX6140 Series Pressure Sensors employ a high accuracy
pressure diaphragm which provides exceptional corrosion
resistance to the most aggressive media. The Differential
Pressure Series uses stainless steel diaphragms for best
performance in double sided wet/wet applications.
The measuring element is a Piezo resistive strain gauge giving a
high electrical output with excellent linearity, and negligible
zero drift.
The information from the sensing bridge is processed by a
specially designed software programme to provide user
configurable information display and a conditioned output signal.
• High accuracy pressure capsule with characterised temperature
compensation incorporating EPROM intelligence to give a
standardised output signal. This simplifies service and
replacement of the sensing element.
• Programmable information display for zero, span, signal offset,
turndown, signal transfer characteristic, engineering units,
signal damping, display suppression, fault mode, mode,
contrast and signal clamp.

5.2
Process Fittings
• Ensure that the pressure rating of the process fittings used is compatible
with the maximum pressure anticipated in the system.
• Isolating valves should be fitted where pressure surges may be anticipated
during commissioning or shutdown.
The sensor will tolerate reasonable levels of contamination and foreign particles
present in the process medium but where conditions are particularly aggressive,
the sensor should be protected with a U-bend or an isolating seal.
5.3
DP Sensors
• Differential pressure sensors must be protected against excessive static pressure

HAZARDOUS AREAS
It is recommended that a direct mounted valve manifold is included in the

convenient mounting of DP sensors.
5.4
High Pressure
• Where the sensor is used on high pressure systems, care should be
taken to isolate or relieve the system pressure before installation or removal.
Ensure that all couplings are fully tightened before applying pressure to
the system.
5.5
Pressure Surges
• High pressure surges in the system can cause permanent damage or
de-calibration to the pressure capsule.
Protect the sensor pressure inlet whenever maintenance work is being carried
out on the system.
5.6
Caution
• Do not insert sharp or metallic objects into the pressure orifice, this may cause
damage to the sensing element. Excessive test pressure applied to the
diaphragm of low pressure sensors may also de-calibrate the output signal.

Mounting Attitude of the Sensor Housing
• In most cases the sensor is not significantly affected
by its mounting attitude.
A small amount of zero shift may be observed in
very low pressure sensors, as a result of gravitational
influence on the diaphragm in some positions.
This can be corrected by calibration of the sensor.

5.9 System Integrity
If a pressure monitoring system should fail for any reason, it is important that the
system is capable of immediately alerting operational staff to this fact.
The sensor will indicate a system failure or mechanical defect and this information
can be utilised to initiate a warning alarm. It is good practice to provide emergency
facilities to protect against the loss of the mains power supply.
Standby batteries can be incorporated with automatic changeover facilities, so
guaranteeing continued operation of the pressure sensing system even in the
event of a plant breakdown as a result of a power supply failure.
Certainly, in critical plants, duplication or triplication of sensors is recommended.
The Trolex TX9042 or TX9044
Programmable Sensor Controller
can be programmed to operate
with sensors in the multiple
voting mode.

5.10 Sensor Management
GROUP I & II
INTRINSICALLY
SAFE
A very important part of an efficient pressure monitoring system is the training of plant
personnel in operation and maintenance of the sensors and the complete
monitoring system. Training facilities can be provided by qualified Trolex application
engineers.
Once a sensor installation is complete, the sensor locations and types should
be formally recorded and a planned test and maintenance procedure instituted.
5.11 Hazardous Areas
Do not disassemble the sensor whilst in the hazardous area or use a sensor
that has a damaged housing in the hazardous area.
